René Kijewski 677d690e2b core: introduce thread_yield_higher(), yield less ... Fixes #1708. Currently involuntary preemption causes the current thread not only to yield for a higher prioritized thread, but all other threads of its own priority class, too. This PR adds the function `thread_yield_higher()`, which will yield the current thread in favor of higher prioritized functions, but not for threads of its own priority class. Boards now need to implement `thread_yield_higher()` instead of `thread_yield()`, but `COREIF_NG` boards are not affected in any way. `thread_yield()` retains its old meaning: yield for every thread that has the same or a higher priority. This PR does not touch the occurrences of `thread_yield()` in the periph drivers, because the author of this PR did not look into the logic of the various driver implementations.		2014-10-24 00:09:56 +02:00
